The absence of generally assumed strong correlations between striatal dopamine synthesis capacity and simple indices of working memory capacity, trait impulsivity, and spontaneous eye-blink rate warrants caution for using these traits as proxy measures to replace direct striatal dopamine assessments.

Involuntary eye movements that keep images positioned over the center of the retina are synchronized with blinks to minimize disruption to vision.

The brain ensures that blinks do not disrupt vision by deleting signals that represent discontinuities in visual input, rather than by recreating the missing input.

Similar to spontaneous eye blinks perceptual stability, despite small saccades, is related to actively silencing transients in the high-level ends of both ventral and dorsal visual cortices, while activity in low-level visual cortex remains unstable.

Dopamine neurons signal value prediction errors (VPEs) integrating information about both reward and aversion, in low reward contexts, whereas VPEs in some dopamine neurons are distorted in high reward contexts.

Non-invasive disinhibition of the oculomotor system shows that ongoing preparatory activity in the superior colliculus has movement-generating potential and need not rise to threshold in order to produce a saccade.

Dominant mutations in Arl3, linked to inherited retinal dystrophy, disrupt the active Arl3-GTP ciliary gradient and cause a defect in rod photoreceptor nuclear migration that can be rescued by elevating ciliary Arl3 activity or reducing aberrant non-ciliary Arl3 activity.

When conscious visual perception changes, the observer's pupils simultaneously signal the accompanying change in visual cortical representation, and specific neuromodulatory activity that helps translate the altered visual experience into behavior.

Shared traits in gaze patterns and brain activations between marmosets and humans during Theory of Mind animations reveal cross-species cognitive similarities.

In a forced decision between two identical percepts, subjects preferentially rely on inferred internally generated over veridically seen percepts.
